NCERT’s new Class 8 maths book now calls it the Baudhayana–Pythagoras Theorem, crediting ancient Indian scholar Baudhayana.

For generations, Indian students have learnt it simply as the Pythagoras Theorem. In a quiet but significant shift, the Class ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school. When you ...

Pythagoras' theorem can also be used to solve 3D problems. You often need to use Pythagoras' theorem more than once in each problem as we create extra right-angled triangles in the 3D shapes. First ...

This is an updated version of a story first published on May 5, 2024. For many high school students returning to class, it may seem like geometry and trigonometry were created by the Greeks as a form ...
